Facebook Open Sources Insights Script For Developers

"The application, which runs on Google AppEngine, uses the
Facebook Graph API to pull data from Facebook. The level of insight
is pretty impressive. For example, Facebook makes a distinction
between the number of Page stream views versus unique views (which
I would assume is the number of users that viewed your stream
story). While it doesn't appear as though the new Insights tools
are rolled out to all users yet, developers can immediately start
leveraging the Insights product for their own internal use, or to
build third-party analytics services."
